Buffalo National River, Arkansas, United States

Color Zone: Dark BlueIs Camping Allowed? YesEntrance Fee? NoDescription: Far away from any towns, the skies here are very dark. Some of the sky will be obstructed by cliffs and trees, depending on where you set up. But since it’s so heavily forested in the Ozarks, it’s difficult to find a better spot than the Steel Creek Campground. Another nearby spot that may be good for stargazing is the elk viewing area across from Lost Valley Rd.
